DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments are provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.

With reference to the figures, an article of footwear 10 is provided and includes an upper structure 12 that selectively receives a foot 14 (FIG. 2) of a user and a sole structure 16 providing support and cushioning to the foot 14 during use.

The upper structure 12 includes a rear 18, a vamp 20, a toe box 22, and a liner 24, which are joined together through stitching 26, high-frequency welding, and/or via an epoxy. The upper structure 12 is fastened to the sole structure 16 for securely retaining the foot 14 and may be formed of a material that concurrently protects the foot 14 and provides ventilation for cooling and removing perspiration.

The rear 18, or back portion of the article of footwear 10, protects the wearer's calcaneus or heel bone and minimizes relative movement between the foot 14 and the article of footwear 10 during use. To this end, the rear 18 may include a heel counter 30 providing stiffening properties for the rear of the article of footwear 10 and a topline 32 for bringing the rear 18 into contact with the foot 14.

The vamp 20 generally covers the instep and toes of the foot 14 and further includes a tongue 34 and a lace 36. The vamp 20 is typically separated into a medial portion 38 (FIG. 2) and a lateral portion 40 (FIG. 1), which correspond to the medial and lateral sides 42, 44 of the article of footwear 10. As shown, the vamp 20 is made from a variety of materials such as leather and synthetic materials, which are strategically placed for both functional and aesthetic purposes. For example, in one construction, a synthetic mesh material 46 is placed over a front portion of the foot 14 to allow air to move into and out of the article of footwear 10 to cool the foot 14 during use.

The tongue 34 is disposed generally between the medial and lateral portions 38, 40 and may be formed from the same or different material as the medial and lateral portions 38, 40. The tongue 34 improves the overall aesthetics of the article of footwear 10 and protects a top portion of the foot 14 by preventing the lace 36 from rubbing against the top portion of the foot 14.

The lace 36 extends through opposing lacing holes 48 formed in or attached to the upper structure 12 and draws the medial and lateral portions 38, 40 of the vamp 20 towards one another for securing the vamp 20 around the foot 14. The toe box 22 covers and protects the front portion of the foot 14 and may be formed from a relatively durable material to protect the upper structure 12 from scuffing and to protect the front portion of the foot 14 during use.

The liner 24 is disposed generally within an interior portion of the article of footwear 10 and is positioned such that when the foot 14 is received within the article of footwear 10, the liner 24 is in direct contact with portions of the foot 14. The liner 24 is constructed from a generally soft material and is formed over a layer of cushioning material to concurrently provide the foot 14 with a degree of comfort and protection during use.

With particular reference to FIG. 3, the tongue 34 has a generally rectangular main body portion 50 with a first end 52 and a second end 54. The first end 52 is attached to the medial and lateral portions 38, 40 of the vamp 20 and the second end 54 is movable relative to the upper structure 12. The length of the main body portion 50 extends along a longitudinal axis 56, which extends between the first end 52 and the second end 54.

The tongue 34 further includes a horizontal lace-retention feature 58 located proximate the longitudinal axis 56. The lace-retention feature 58 is generally rectangular with a pair of outboard ends 60, 62 attached to the main body portion 50 of tongue 34 by any suitable means such as stitching, high-frequency welding, and/or via an epoxy. The length of the lace-retention feature 58 extends along a latitudinal axis 64 of the main body portion 50. Attaching the outboard ends 60, 62 to the main body portion 50 forms a horizontal opening 66 between a top surface 51 of the tongue 34 and an inner surface 59 of the lace-retention feature 58 that accepts the lace 36 therethrough in a direction substantially parallel to the longitudinal axis 56.

A vertical lace-retention feature 68 is attached to the tongue 34 below the horizontal lace-retention feature 58 in a similar fashion to that of the horizontal lace-retention feature 58. The lace-retention feature 68 is generally rectangular with a pair of outboard ends 70, 72 and has a length extending along the longitudinal axis 56. The lace-retention feature 68 forms a vertical opening 74 between the top surface 51 of the tongue 34 and an inner surface 69 of the lace-retention feature 68 that accepts the lace 36 therethrough in a direction substantially parallel to the latitudinal axis 64.

The lace 36 is strung through the lacing holes 48 and the lace-retention features 58, 68 to maintain the tongue 34 in an upright and centered position relative to the medial and lateral portions 38, 40. The lace 36 extends from the lacing holes 48 on the medial side 42 in the general direction of the latitudinal axis 64 and through the vertical opening 74 of the lace-retention feature 68 to the lacing holes 48 on the lateral side 44. Likewise, the lace 36 extends from the lacing holes 48 on the lateral side 44 through the vertical opening 74 of the lace-retention feature 68 to the lacing holes 48 on the medial side 42.

A generally arcuate portion 76 of the lace 36 extends from the lacing holes 48 on the medial side 42 upward through the horizontal opening 66 of the lace-retention feature 58 and returns to the lacing holes 48 on the medial side 42. Likewise, a generally arcuate portion 78 of the lace 36 extends from the lacing holes 48 on the lateral side 44 upward through the horizontal opening 66 of the lace-retention feature 58 and returns to the lacing holes 48 on the lateral side 44. The horizontal opening 66 is oriented such that the arcuate portions 76, 78 do not overlap. Rather, the arcuate portions 76, 78 oppose one another in an area of the horizontal opening 66.

The interface between the lace-retention feature 58 and the portions 76, 78 functions to keep the tongue 34 centered. Specifically, the lace 36 cooperates with adjacent lacing holes 48 and with the lace-retention feature 58 to prevent movement of the tongue 34 relative to the medial and lateral portions 38, 40 by transmitting a force applied to the tongue 34 (in a direction substantially parallel to axis 64) to the respective portion 38, 40. By positioning the arcuate portions 76, 78 in opposition to one another, any force applied to the tongue 34 in either direction along axis 64 will be transmitted to the medial or lateral portion 38, 40 via interaction between the lace 36, adjacent lacing holes 48, and lace-retention feature 58 and, as such, will restrict movement of the tongue 34 relative to the medial and lateral portions 38, 40. The lace-retention feature 58 acts against the portions 76, 78 to prevent the tongue 34 from moving toward the lateral and medial sides 44, 42, respectively.
